I have become curious about something. There are a some translations
of Il Libro dell' Arte by Cennino Cennini, the first [that I know
of'] by a woman named Merrifield, a later one by a German individual
whose name I don't have, and, most recently, one by Daniel V. Thompson.

Were these translations made from Cennini's nanuscript? Where did
each of these individuals get copies of or access to the original
document? Where is the manuscript presently?
